To get to the blacksmith jump on the mini wall on the side of the building, then wall jump up to the air blowing thing. Jump from that up to the window and from the window to the top of the Blacksmith.
To get on the Inn Entrance and on the very top go to the left side of the door. There is a large colum connected to the building ( duh ), This is where the noobs get confused, you dont walk straight up the corner, you go to the side and jump up on those cracks you can see in the texture, do this while walking until as high as possible, then run off/runjump real quick onto the front door of inn. To get on the roof... once you are on the entrance turn around and look at the inn, on your left there is a rafter sticking out, jump up between that and the gutter/edge of the roof, get stuck and jump up. Then you are on top of the Inn.
